Harbinger of Doom

<A discordant note can be detected in A'dal's 'voice'.> Prince Kael'thas has chosen his warden poorly, and now the entities that we kept locked up within the Arcatraz are breaking free. One in particular, a servant of the Old Gods known as Harbinger Skyriss, seeks to usher in his masters' vision of conquering all of the worlds in the universe. <name>, you must not allow him to escape. Return to Tempest Keep, enter the Arcatraz, and slay Harbinger Skyriss before it is too late!
